Phase shifters are devices used to change the phase of a transmission network. An ideal phase shifter has very small insertion loss and almost the same loss in different phase states. This is to achie
[size=4][color=#a0522d]Capacitor is a kind of energy storage element, which has the characteristics of "blocking direct current and passing alternating current, negative low frequency and passing high
An antenna array is an antenna system consisting of a group of transmitting elements. If these antenna elements are identical, such as in an omnidirectional array, and if they are spaced equidistantly
Abstract: This paper introduces a low-noise, broadband intermediate frequency amplifier monolithic integrated circuit based on high-frequency low-noise bipolar shallow junction process.The design idea
